One of the main objectives of this study is to develop a generic thermo-mechanical durability model for Pb-free solders.
这项研究的主要目标之一是建立一个通用的热机械为无铅焊料的耐久性模型。

There exist a partly thermodynamic recrystallization, and superplastic grains appear in the thermo-mechanical affected zone.
机械热影响区存在部分动态再结晶和较明显的塑性变形晶粒。
3
Based on FEM, an axis symmetric finite element electro-thermo-mechanical model in the formation of molten core of resistance spot welding is introduced.
